Types of boilers explained

There are three main types of condensing gas boilers: combi boilers, system boilers and conventional boilers (also called traditional, regular boilers, open vent or heat only boilers).

Before deciding which of these boiler system to proceed with you should always consider:
     The size of the property & and planned extensions
     The current boiler type & pipework in your property
     The number of showers & the number of bathrooms
     The area’s water pressure
     The type of property
     If the boiler needs to be solar compatible

Each type of condensing boiler has a range of unique properties to suit these requirements.

To help provide you with some insight into which boiler replacement option is the most practical choice for your own home take a look at our guide below. We share how each boiler type works, their advantages and what kind of homes they work best in

Regular Boilers

House Layout Diagram

The heat-only standard boilers have separate water cylinders, operating through your central heating system to provide a high demand of hot water.

Very similar features to a system boiler but a conventional boiler is better suited for older properties as older radiator systems might not be able to cope with the high water pressure from other boiler types. Conventional boilers are also a good option for low pressure water systems.

You Can Use Multiple Taps At Once
As the water comes from a water cylinder, you can use multiple sources such as taps and showers, without experiencing any effect on water pressure or temperature.

Old system replacement
When it comes to replacing the heating system in an older property, a regular boiler can be a good option as it requires minimal changes to the pipework if any.

Compatible With Solar Thermal
Conventional boilers are compatible with solar water heating systems for a lower carbon footprint and lower energy costs.

Great For Low Water Pressure Areas
If you live in a low water pressure a conventional boiler may be the best solution as other means can be utilised to increase the domestic water performance in the property e.g. the use of a pump.
